Title: Phase detecting circuit
Inventor: MATSUDA NAOKI
IPC: H04N9/45
Filed: 1993-02-26
Abstract: PURPOSE:To stabilize a phase detection output and hold PLL operation stable even when phase detection is performed in a period wherein a burst signal is omitted. CONSTITUTION:The loop of an adder 301, latch circuits 303 and 304, and an inverter 302 samples and integrates input data in a certain period and outputs its final phase detection value through a detection characteristic selecting circuit 306. The circuit 306 is switched so as to derive a maximum value output or minimum value output by using the output of the latch circuit 303 when the final phase detection value is larger than a specific value or smaller than the specific value. Here, shift registers 307 and 309 and an OR circuit 309 decide the continuity of the signs of respective phase detection values, and considers that there is a burst and outputs the final phase detection value when the same sign succeed, but decides that there is no burst and stops the phase detection output when the signs are unstable.

Title: Manufacture of lead frame for semiconductor device
Inventor: MICHII KAZUNARI
IPC: H01L21/48
Filed: 1980-03-24
Abstract: PURPOSE:To allow even a small quantity of lead frames to be punched, by a method wherein a lead frame is manufactured by using a blanking die for working the common portion to every frame and a blanking die for working the exclusive portion unique to each frame. CONSTITUTION:Only the portion, e.g., showed by diagonal lines in (a), common to every frame is then worked by using a die for common work. The frame having  finished the work on said common portion is worked on the portion, e.g., shown by diagonal lines in (b), by using an exclusive die unique to each frame. Thus, by simply prepaing one die for common work and several types of exclusive dies unique to frames, the cost of the dies can be largely reduced, so that the frame cost can be made lower.

Title: Vane wheel for water meter and rotation-testing apparatus of indicating unit
Inventor: SAITO MASAHARU
IPC: G01F25/00
Filed: 1993-02-26
Abstract: PURPOSE:To provide a testing apparatus wherein the rotational performance of an indicating unit and a wing wheel can be inspected with high accuracy. CONSTITUTION:When the rotating torque of an indicating unit 13 is an extremely small value, a magnet gear 132 or the like is turned smoothly, accordingly, a wing wheel 110 is turned smoothly, and the output of a wing-wheel sensor 12 becomes the same as when the indicating unit 13 is not attached. When the rotational performance of a gear inside the indicating unit 13 is abnormal, the magnet gear 132 is not turned so as to smoothly follow a driving magnet 114 for the wing sheel. Thereby, the rotational abnormality of the magnet gear 132 is reflected on the rotation of the wing wheel 110 which has been coupled magnetically to it, the rotation of the wing wheel 110 causes a very small change, and the output pulse cycle of the wing-wheel sensor 12 becomes irregular. Consequently, when the output data of the wing-wheel sensor 12 is analyzed, whether the rotational performance of the indicating unit 13 is good or not can be judged.

Title: Surface cleaning method and surface cleaning powder coating cabin
Inventor: BAANAADO DEINKERU
IPC: B08B1/00
Filed: 1985-02-26
Abstract: A powder coating booth has a bottom surface on which powder is collected and from which the powder should be removed. Two scrapers are supported on a transport device which move them together. Each scraper is movable from its respective end of the booth toward a central collection region. Since the scrapers are moved simultaneously, one is moving toward the collection region while the other is moving away. As a scraper moves toward the central collection region, it scrapes powder from the surface and delivers it to the collection region. Each scraper swings into an operating, surface scraping position as it moves from its respective end of the booth toward the collection region, and swings into an upraised, non-scraping position, as each moves from the collection region back to the end region. A cable with scraper engaging flights on it is movable for engaging the scrapers and for moving and for swinging them. The scraper moving cable exits from the booth through a wall and a gas nozzle external to the wall blows powder off the cable and back into the booth.

Abstract: PURPOSE:To suppress flux leakage at bridge section by jointing a nonmagnetic reinforcing boards, which are bridged on the inner circumferential side and parts superposed on the end faces of respective pole pieces are projecting radially on the outer circumferential side, to the end face on one side of inner ring pole section. CONSTITUTION:An inner ring pole section 10 to be fitted to an outer ring yoke section 5 comprises a plurality of pole pieces 7 coupled with bridge sections 9. A reinforcing board 11 is made of a nonmagnetic body having higher strength than the inner ring pole section 10, where the inner ring side is coupled through a bridge type coupling section 12 and sections 13 to be superposed on the end faces of the pole piece 7 and coincide in profile with the pole piece 7 are formed on the outer circumferential side. The reinforcing board 11 is jointed to the end face on at least one side of the inner pole section 10. Since the bridge section coupling between the pole pieces at the inner ring pole section is made narrow, flux leakage at the bridge section is suppressed and the motor efficiency is improved.

Filed: 1987-02-20
Abstract: PURPOSE:To enable accurate measurement of a displacement between gauge marks, by using an area image sensor as image sensor to trace a gauge mark without missing from a field of view. CONSTITUTION:In a tensile test, it is necessary that the level of a slicing signal should be lowered from a slicing level generation D/A device 14 because contrast against the texture of a test piece lowers gradually with the stretching of a gauge mark 2 as the test piece 1 extends. As the gauge mark 2 moves with the extension of the test piece 1, an command is sent from a CPU 16 to a motor 20 through an I/O port 15 and with the driving of the motor 20, a tracing camera 3 traces the gauge mark 2. The camera 3 outputs an image formed with a lens 5 by a CCD image sensor 6 as reading video signal. The CCD 6 uses an area image sensor and reads an image formed two-dimensionally in the direction XY. This enables the tracing of the gauge mark 2 without missing with the expansion of a view of field as XY-way 2-D image.
